The moment Sargent captured in "Carnation, Lily, Lily, Rose" feels steeped in an elusive light, a twilight scene where two children, Dolly and Polly Barnard, gently tend to Chinese lanterns in a garden. Their light blonde hair was specifically chosen to enhance the painting's overall color scheme. Sargent's dedication to recreating a unique light effect, inspired by Chinese lanterns seen at dusk, meant he often worked en plein air, sometimes for only a few minutes each evening across two years (1885-1886). The intense focus on this delicate task is heightened by the composition; Sargent actually removed two feet from the canvas's left side, resulting in an almost square format that concentrates the viewer's attention. Even when autumn arrived and the natural flowers withered, he replaced them with artificial ones, prioritizing the specific visual effect over strict realism. The painting's title, unexpectedly, derives from an 18th-century song, "The Wreath," which suggests a charming, perhaps musical, atmosphere that belies the artist's meticulous and drawn-out effort to pin down that fleeting light. This slow, almost obsessive process to capture such a brief, tender moment makes the final image feel like a delicate, cherished secret.
